Same input.
Same output.
Every time.
A deterministic, replayable decision path for back-office work — every decision pinned, retrievable, and signed. Built on CashCtrl as the system of record, with Swiss/EU data residency by design.
book invoice #2026-0473 · CHF 4,820.00 · VAT 8.1% · acct 1100 computing… Run it. The signature never changes — until you switch to a stochastic model.
Stochastic AI agents can't be audited.
A DLM is auditable by construction.
The exact model and weights behind every decision are recorded, never silently upgraded.
The same sources are read in the same order, so the same input resolves the same way.
Every answer is anchored to its model version, prompt version, retrieved sources, and reasoning.
One deterministic engine. Three ways it shows up.
Back-office work
Bookkeeping, payroll, contracts, reconciliation — built to run deterministically on CashCtrl, with the judgement kept with the accountant you already have.
